Brennan Boesch underwent season-ending surgery on his right thumb Tuesday.
Boesch will continue to travel with the team, but will need 10-12 weeks of recovery time. The 26-year-old outfielder batted .283/.341/.458 with and 16 homers, 54 RBI and a .799 OPS over 472 plate appearances this season.
He's been out since the last week in August but his season is officially done for. Boesch posted good numbers and will be missed come playoff time. He was one of the very few lefties they had in that lineup.
